CATCH-BASIN RECEIVING-HEAD.

SPECIFICATION forming part of Letters Patent N0. 774,846, dated November15, 1904.

Application filed April 25, 1903. Serial No. 154,211. (No model.)

To all whom it may concern:

Be it known that 1, AUGUST W. KURZ, a citizen of the United States, anda resident of Cleveland, in the county of Ouyahoga and State of Ohio,have invented certain new and useful Improvements in Catch-BasinReceiving-Heads, which improvements are fully set forth in the followingspecification.

This invention relates to improvements in structures of that classemployed in connection with catch-basins or analogous structures, suchas manholes or other openings into subterranean vaults, and the sameserving to control the entrance thereto.

I The object of this invention is to provide a structure of thecharacter indicated which shall be simple and inexpensive as regardsconstruction, durable, efiicient, and reliable in practical service,which shall embody elements relatively adjustable to suit conditionsinvolved in the installation of the head for service, together withelements whereby are secured important results in connection with thedetachable lid made use of and the latters application to and removalfrom the main member of the construction, which shall be attractive inappearance, and which shall possess certain well-defined advantages overprior analogous structures.

The invention consists in the novel disposition and relative arrangementof the various cooperating parts thereof, whereby the attainment of theabove object is rendered practicable in certain combinations and incertain details of construction, all of which will be specificallyreferred to hereinafter and set forth in the appended claims.

The invention is clearly illustrated in the accompanying drawings,wherein similar referenoe characters denote corresponding partsthroughout the several views.

As to said drawings, Figure 1 is a plan view of a catch-basinreceiving-head embodying my said improvements. Fig. 2 is a sideelevation of said receiving-head. Fig. 3 is a central verticallongitudinal section along the line a a of Fig. 1. view of saidreceiving-head, and to more clearly disclose the operative relationexisting Fig. 4 is a perspective 1 between the manhole of theconstruction and the detachable lid employed for spanning said manholein practice said lid is shown as having been displaced from its normalposition and arranged obliquely across said manhole. Fig. 5 is a detailview showing automatic lock mechanism employed in connection with thedetachable lid of my improved receiving-head, said View being mainly insection on the line I) Z) of Fig. 6 and the scale being enlarged. Fig. 6is a detail elevation of said lock mechanism, the scaleconforming tothat of Fig. 5. Fig. 7 is a bottom plan view of a detachable lid forsaid receiving-head, said lid being modified somewhat as to details ofconstruction; Fig. Sis aside elevation of the inverted lid shown in Fig.7

In a general sense my invention comprises an extended main member, ahood adjustably conjoined with said main member, the latter presentingto said hood under all degrees of adjustment thereof relatively to saidmain member a point of supporting resistance substantially in the sameplane with the point of support on the hood.

It further comprises a main member forming a manhole for theconstruction and a detachable lid for spanning said manhole, said lidbeing provided with a guard, whereby its passage interiorly of saidmanhole beyond a prescribed plane is prohibited.

It still further comprises a main member forming a manhole for theconstruction, a de tachable lid for spanning said manhole, andautomatically-operating mechanism for looking said lid in positionthrough the adjustment thereof for service at said manhole.

In carrying out my invention, reference being bad tow the accompanyingdrawings, I employ a main member 2, forming the manhole for thestructure as a whole, said member having a base-flange 2 and beingextended rearwardly to receive a hood 2", said parts, respectively,being readily produced from metal by the process of casting.

7 The hood 2 has an intake 3 and is rearwardly extended, substantiallyas shown, to provide ample sweep for such waste or surface Water as mayin practice seek the interior of the basin in connection with which myimproved receiving-head may be used, such water primarily entering thehood 2 by way of its intake 3. This rearwardly-extending feature of thehood 2 is particularly advantageous where the chief intake for the wasteor surface water aforenamed is provided as an element of said hood.

The hood 2 terminates at its lower portion in a depending lip 3, offsetinwardly to nicely escape the vertical adjacent wall of the member 2when said hood is in position for service.. This offsetting of the lip 3results in the formation of a shoulder 3", preferably coextensivehorizontally with the rear portion and opposite sides of the hood 2, andthis applies also to the lip 3, the latter serving, essentially, toclose the space intervening between the upper edge of the adjacentportion of the member 2 and the shoulder 3 under certain adjustments ofsaid hood with respect to the member 2. For the purpose of effectingthis adjustment of the hood 2 I interpose between the shoulder 3 and theupper edge of the adjacent wall of the member 2 one or more separatingsegments, strips, or pieces 4, the same being here shown each in theform of a flat block constructed from metal, cement, or other suitablematerial. I have shown each of the separator-blocks 4 as beingdovetailed in place for service, its upper and lower edges beingoppositely beveled, and the shoulder 3 and upper adjacent edge of themember 2, respectively, being correspondingly shaped, and where this.feature is availed of a distinct fastener in the form of a bolt and nutor otherwise for retaining purposes in connection with said separator isnot required.

It will be seen that the separator-blocks 4 may be replaced by othersvarying therefrom in height and that the hood 2 may be accordinglyraised or lowered with respect to the member 2; but under each and alldegrees of such adjustment of the hood 2 the point of support on saidhood is always substantially in line with the line of supportingresistance of the main member no matter what the width or height of theseparating-blocks may be. Thus the hood 3 has a firm and, in conjunctionwith the bolts 5, a rigid bearing at all adjustments on the wall ofmember 2 itself. By this means all shearing tendency is avoided and thehood given a firm support at all elevations above the base member.

The hood 2 and member 2, with the separator or separators 4 interposedbetween them, may be rigidly secured together in any appropriate manner,though to this end I have shown said hood and said member as beingprovided the one with a lateral eye-clip 4' and the other with a likeeye-clip 4, said eye-clips 4 4 being arranged in vertical alinement andthrough which extends a headed bolt 5, threaded to receive a nut 5,these features-of the construction being accordingly arranged so thatdue I casting.

homeward turning of the nut 5' will result in the rigid securingtogether of the hood 2 and member 2, with the separator or separators 4between them, as hereinbefore mentioned. It will be understood that thefasteners just described or parts analogous thereto may be duplicated atany desired point or points along the outer or inner side of the hood 2and member 2, as clearly indicated in Fig. 3 of the drawings.

Interiorly of the member 2, forming the manhole of the generalstructure, and near the upper extremity of the exposed portion of saidmanhole there is arranged a seat 5, adapted to receive and support adetachable lid 6, the latter when in position spanning the manholeaforenamed. The lid 6 may be substantially'integral, as indicated inFig. 4 of the drawings, and in this connection the importance of therearwardly-extending feature of the hood 2 becomes clearly apparent, asin such case practically the entire volume of the waste or surface waterto be taken care of must enter the intake 3. Said lid may, however,approximate the character of a grate, as

indicated in Fig. 7 of the drawings, and under such conditions therearwardly-extending feature of the hood 2" is not strictly essential,although desirable, as in the event of an accumulation of wastematerials or substances at the grate-like lid aforenamed sufficient todivert the volume of waste or surface water to be cared for, or asubstantial portion thereof, into the hood 2" by way of its intake 3.

To the end that the lid 6 may not be passed accidentally orintentionally interiorly along the manhole. formed by the member2 beyondits seat 5", and accordingly into the basin in connection with which thestructure as a whole is used, I provide said lid with a guard,(designated as an entirety in the drawings by the character F.) Thisguard may be formed as a separate attachment, as from segments ofangle-iron bolted or otherwise secured together, Fig. 3, and thereafteras a completed attachment secured to the lid 6, as by means of bolts 6,or when preferred the various elements of said guard may be formedintegral with the lid 6, Figs. 7 and 8, as by the process of Morespecifically, said guard comprises a looped member 7, traversing theunder side of the lid 6 and projecting rearwardly therefrom, opposingside members 7 7" depending from said looped member, and a transversemember 8 connecting said side members, the several guard membersm.entioned being suitably braced, as indicated in the drawings. Theguard F serves to materially strengthen the lid 6 in addition to itsfunction of preventing undue passage of said lid inwardly along themanhole of the structure.

If the general contour of the manhole of the structure were such as toconform substantially to a true circle and the lid 6 were shapedaccordingly, it would not be a difficult problem to arrange the seat 5so as to prevent undue inward displacement of said lid, suchconstruction being common and well known; but for manufacturing,commercial, and other substantial reasons it is quite inadvisable toprovide a structure of the general character herein described with amanhole and lid therefor of the general contour, respectively, abovementioned. The reverse, however, is true where such structure isprovided with a manhole and lid therefor of a general contour,respectively, other than circular. For illustration, if said manhole beof an angular general contour, as indicated in the drawings, or of anelliptical general contour and the lid therefor be accordingly shapedinward displacement of said lid may in the absence of provisions to thecontrary, as the guard F, follow certain manipulations of the lid, andsuch manipulations may be accidental or intentional, as will be readilyunderstood. Accordingly I provide my improved receiving-head with amanhole of a general contour other than circular, and the lid 6therefor, conforming substantially in contour with the contour of saidmanhole, I provide it with said guard.

In applying the lid 6 for service its front portion is held somewhatupwardly from the member 2, while its rear portion is eased downwardlyto the seat 5", the looped member of the guard F accordingly projectinginto thehood 2", whereupon the front portion of the lid is easeddownwardly until said lid is brought to a fair seating engagement atproper edges thereof with the seat 5", the de-' pending portion of saidguard under such conditions pro ecting downwardly into the member 2 andthe rearward prolongation? of the. guard F coming against the stop 9"on'the.

hood, as shown in Fig. 3, for a purpose to be described hereinafter.Under any other adjustment of the lid 6 with respect to the manhole ofthe structure contacts are effected between variable points of the guardF and lid 6, jointly or separately, and like points of the member 2 andhood 2", jointlyor separately, thus preventing the passage of lid 6inwardly into the manhole beyond the seat 5. In this connection 8 is ashouldered latch movable upwardly and downwardly along a plane inclinedrearwardly and upwardly from the front of the member 2. The upwardmovement of said latch is effected under manual effort duly applied andthe downward moveedge. The latch 8 works in the socket 9, the

latter being open at its front to permit due projection of theshouldered portion of said latch therefrom to a point underneath theseat 5" for a locking effect under normal conditions of the parts, asshown in full lines in Figs. 5 and 6. Under the conditions of the partslast named displacement of the lid 6 upwardly or otherwise from its seat5" becomes impracticable until said latch shall have been properlyadjusted as to the position indicated in dotted lines in Fig. 5 and asin opposition to its own gravity.

To accomplish the adjustment of the latch 8 last referred to, anysuitable key or implement, hooked or otherwise, duly shaped at one end,may be passed downwardly through the lid 6, Fig. i, by way of thekeyhole 9, formed therein, or downwardly through the grate-like lid 6,Fig. 7, by way of one of the openings formed in the latter, saidimplement being adapted to permit the application of a lifting force tosaid latch, as will be clearly understood. Under such upwardly-displacing action of the latch 8' (said latch being accompanied at all times bythe shaft 8) its depending portion rides upwardly along the upwardly andrearwardly inclined back of the socket 9, by which said latch is held inposition under normal conditions, so that its shouldered portion takesunder the seat 5" for a locking effect, as herein stated.

It will be seen that as the projecting loop 7 when the lid is inposition bears under and against the stop 9 on the rear inside face of.the hood that end of the lid is prevented from tilting up,,thus actingin conjunction with the lock to prevent any raising of the lid after itis in position on the manhole, as clearly shown in Fig. 3.

The operation of my improved receivinghead will be apparent from theforegoing de scription thereof, and it will be seen that theconstruction herein set forth may be modified to some extent withoutmaterially departing. from the spirit and principle of my invention.

While my invention is particularly adapted to catch-basin heads, yetitis suitable for use with other forms of manholes or for use with anyvault or conduit having an opening therein. Having fully described myinvention, what I claim, and desire to secure by Letters Patent, is
